An old sample of wood from an archaeological excavation was found to have a radioactivity of about 140.8 counts per minute due to 14C (t1/2=5730 years) as against 281.6 counts per minute for that of a freshly cut piece of wood. What is the age of the old sample of wood (in millennia, 1 millennium= 1000 years)? |
